I-35 will be closed throughout north Central Austin overnight Feb. 15 as crews install an overhead sign bridge in conjunction with the I-35 at 51st Street project.

The Texas Department of Transportation will close the northbound upper deck at 15th Street beginning at 9 p.m. with traffic diverting to the lower deck, according to a TxDOT news release.

Traffic on the lower deck will be reduced to one lane at 11 p.m. and detour to the I-35 frontage road at Exit 237B, or the 51st/Cameron Road exit. To re-enter the I-35 main lanes, motorists can take the entrance ramp near Barbara Jordan Boulevard.

Starting at 9 p.m., southbound I-35 near US 290 East will be reduced to one lane. A detour will take drivers to the southbound frontage road at Exit 237A, or the Airport Boulevard exit, from 11 p.m.-5 a.m. Motorists can re-enter the I-35 main lanes at the entrance ramp near Airport.

East- and westbound US 290 East connections to southbound I-35 will close at 10 p.m., according to release. Cameron Road will serve as an alternate route.

The I-35 at 51st project adds a southbound lane so that through traffic can bypass the traffic signal, reconfigures entrance and exit ramps, and realigns the southbound frontage road to add a roundabout.

Eyeing a spring 2018 completion date, TxDOT received $16.5 million from the city of Austin and Texas Clear Lanes to fund the project. Visit www.my35construction.org for more information.
